My invention relates to improvements in meters and relates more part1cularly to elec trioal meters ha ving scctionsabutting relatively sta-V removable housings provided with tionary sections, said removable sections be ing usuall over the r as well as' vwith the cordel'.

construction.

With the foregoing in view. the invention resides in after described and being supplemented drawing. Figure improved F i gure in section.

YFigure the novel subject matter hereinclaimed, the description by the accompanying l is a front elevation of a meter in accordance with my invention. 2 is a lower end elevation, partly 3 is a side elevation of one ot the sealingr sleeves which surround the connecting bolts' between the relatively stationary and removable housing sections.'

Figo re 4 .is a plan view of a sealing ring which is interposed between the two housing sections.

In the drawing above briefly described, l

have illustrated a well known form ofmeter having'a. housing which includes a relatively stationary 'section l and a removable sec tion -2r abutting the front side of said section 1 and in The inner most instances formed of glass. edge ot the removable section 2 is formed with a flared flange 3 which encompasses a a ring o ortion of the housing section l and felt is usually interposed-between disk which revolves n the bolts 8 .and "crearah Serial No. 699,032.

the two housing sections, along their tino of contact, 'lhcse felt rings however, are often picked away or cut sullioiently to permit wire or other small instrument to be inserted for the purpose of stopping the rotating disk 5' ot the meter and throwing the, re cording means t3 thereoft out of pla For this soft ring of telt or the like, l, su stituto a ring -l ot steel or other desired hard mate rial, said ring being preleiaoly although notA necessarily stamped into shape 'ln all instances, l provide the outer side ot the ring #l with a rib 7 for disposition at the inner side of the wall of .the removable 'housing section 2, and it will thus be seen that. it is impossible lto insert an instrument between the two sections of the housing.,

Extending from the stationary section 1 of the meter housing, l have shown a pair of bolts 8 which passthrough bolt holes 9 in the front, side ot the removable housing section 2, nuts l() being threaded upon `the outer ends of these bolts. Even though these nuts are usually held by a wire seal, so that they cannot be be loosened sutlioiently some small instrument one or the other ot the openings 9, seas to throw the meter out oiloperation.` To over come this diculty, l provide sealing members for the openings 9, said members be-a ing preferably in the itorm of elongated sleeves il which surround the bolts 8 and have their outerl ends in tight Contact with the front portions of thehousing section il, said front ends ot the' sleeves being prefer* ably provided with integrah outstanding, annular flanges 12 shaped to tightly Vcontact with the removable housing' ,section as shown. i I v The sleeves 1l may be secured in place in any desired manner but l preer to 'provide coiled compression springs 13 surrounding against the inner ends of said sleeves,` asl i ustrated in Fig. 2. These springs are sufeiently strong to prevent any instrument, small enough to be passed through one ot the bolt holes t), at the side of the bolt, :troia forcing the sleeves 11 inwardly, and thus tampering with the in ternal parts of the meter, is prevented It will be seen trom the foregoing tha simple and inexpensive provision has been to permit a wire or made for so improving upon meters ot well known forms, as to prevent the thet't ot curremoved, they een often to be passed througlA I tion. As excellent results may be obtained from the details disclosed, they may Well be followed but within the scope of the invention as claimed, numerous minor changes maybe made.

I claim:

l. In combination with a meter having a stationary housing section, a removable housing section, and a bolt extending from the stationar)v section through an opening in the removable section for holding the latter in place; a sealing member for said opening surrounding said bolt and bearing against the inner side of said removable section` and a hard sealing ring interposed between the two housing sections, said sealf ing member and sealing ring preventing the insertion of a wire or instrument to throw the meter out of play.

2. In combination with a meter having a stationary housing section, a removable housing section, and a holt extending from the stationary section through an opening in the removable section for holding the latter in place; a sealing member for said opening surrounding said bolt and bearing against the inner side of said removable sec tion, said sealing member preventing the insertion of a wire or instrument to throw the meter out of play.

'3. A structure as specified in claim 2; said sealing member comprising a sleeve having an annular outstanding fiange contacting with the inner side of said removable housing' section.

l. A structure as specified in claim 2; together with a spring surrounding said bolt and holding said sealing member tightl'v'v in Contact with the inner side of said removable housing section.

In combination with a meter having a stationary housing section, a remoi able housing section; and a bolt extending-from the stationar)Y section through an opening in the removable section for holding the latter in place: a sealing sleeve for Said openin T surrounding said bolt and having an anntdar outstanding flange bearing against the inner side of said removable section, said sealing member preventing the insertion of a wire or instrument to throw the meter out of play, and a spring surrounding said bolt and holding said sleeve in operative position.

In testimoni` whereof I have hereunto-aflixed my signature.
